ios - 使用 getThumbnailBatch 获取保管箱缩略图

Question

我正在使用 dropbox objc API，并尝试获取特定 dropbox 文件夹中的所有缩略图。

但我完全陷入了 DBFILESGetThumbnailBatchArg。如何启动文件夹中所有图像的路径？

这是我陷入的困境:

    [[client.filesRoutes getThumbnailBatch:<#(nonnull NSArray<DBFILESThumbnailArg *> *)#>] 
setResponseBlock:^(
DBFILESGetThumbnailBatchResult * _Nullable result, 
DBFILESGetThumbnailBatchError * _Nullable routeError, 
DBRequestError * _Nullable networkError) { etc etc..

文档说

DBFILESThumbnailArg *arg = [[DBFILESThumbnailArg alloc] initWithPath:<#(nonnull NSString *)#>];


DBFILESGetThumbnailBatchArg *batchArg = [[DBFILESGetThumbnailBatchArg alloc] 
initWithEntries:<#(nonnull NSArray<DBFILESThumbnailArg *> *)#>];

如何初始化 DBFILESThumbnailArg 的路径列表？

正如您所发现的，the getThumbnailBatch method预计 NSArray<DBFILESThumbnailArg *> ，所以调用它看起来像这样:

NSArray<DBFILESThumbnailArg *> *entries = @[[[DBFILESThumbnailArg alloc] initWithPath:@"/test1.jpg"], [[DBFILESThumbnailArg alloc] initWithPath:@"/test2.jpg"]];
[[client.filesRoutes getThumbnailBatch:entries]
 setResponseBlock:^(DBFILESGetThumbnailBatchResult *result, DBFILESGetThumbnailBatchError *routeError, DBRequestError *networkError) {
    if (result) {
        NSLog(@"result:");
        NSLog(@"%@", result);
    } else if (routeError) {
        NSLog(@"routeError:");
        NSLog(@"%@", routeError);
    } else if (networkError) {
        NSLog(@"networkError:");
        NSLog(@"%@", networkError);
    };
}];
